Application led ITanuary 7, 1920. Serial No. 349,904;

To all fw izo/m t may concern:

Be it known that l, HULDRnroH A. Bonn- MAN, a citizen of the UnitedStates, residing at Milwaukee, county of Milwaukee, vand State oflWisConsin, have invented new and useful Improvements in Power-DrivenShoe- Shine Brushes, of whichthe following is a specification.

This invention relates to motor driven shoe shine brushes. i

lt has been found that when Va rotary brush is used to polish shoes thatthe proper shine cannot be secured by rotating the brush in onedirection only and thereby brushing the shoes in one direction. It is,therefore, an object of this invention to provide a rotary shoe shinebrush having means whereby the alternate 'brushing of the shoes inopposite directions is secured.

A further object is to provide a small, light weight power driven shoeshine brush with the parts so arranged that this alternate brushing maybe secured by a relatively small movement of the device.

` ln the drawings-- Figure 1 is a partial sectional view of one form ofthis device.

Fig. 2 is an end view of Fig. 1.

Fig. 3 is a view similar to Fig. 1 of another form of this device.

Fig. 4 is a transverse sectional view of a further form of this device.

Fig. 5 is an end view of the structure shown in Fig. l with parts brokenaway to illustrate the arrangement.

Fig. 1 shows a casing 1 within which is housed a pair of juxtaposedaxially alined brushes 2 and 3. A handle 1 is secured to the casing 1and a flexible shaft 5 passes through such handle. This shaft, ofcourse, may be an outer casing and an inner flexible shaft proper if sodesired. The `flexible shaft 5 is fastened to a shaft 6 which ispivotally mounted in bearings 7 formed in the casing 1. This shaftextends through the hubs 8 and 9 of both of the brushes, but is keyedonly to the hub 8, the hub 9 turning freely upon such shaft. It isunderstood, of course, that these hubs may be of wood, metal lined ifdesired. The hubs 8 and 9 have pulleys 10 and 11 respectively securedthereto. From these pulleys belts 12 and 13 extend to similar pulleys 14and 15 rigidly mounted upon a jack shaft 16 arranged in the upper partof the casing 1.

When the brushes are driven by .a motor u attached to the other end ofthe` flexible shaft 5, the brush 2 is driven directly from the shaft 6,the pulley 1() rotating therewith. This pulley, through the medium ofthe belt 12, the cross belt 13 and the pulleys14, 15 and 11, transmitsmotion'to the brush `3 `and causes such brush to rotate in the oppositedirection to the brush 2. v

Fig. 3 shows a second form of the device in which the jack shaftl isreplaced by a driving shaft 17 and in which Vthe handle through whichsaid shaft 17 passes is located adj acent the upper portion of thecasing. A second stationary shaft 18 is mounted` adjacent the lowerportion `of the casing and carries thereonthe hubs 19 and 20 of twobrushes 2O and 21 respectively. Pulleys 22 and 23 rigidly fastened tothe shaft 17 transmit rotary motion to the brushes 20 and 21 through themedium of pulleys 24 and 25 secured respectively to the hubs of suchbrushes, the respective pairs of pulleys being connected by a belt 26and a cross belt 27.

Fig. 4: shows a further form of the invention in which the driving shaft28 passes through the handle and through the lower portion of thecasing. A brush 29 has its hub 30 secured rigidly to the shaft 28 whilea second brush 31 has its hub 32 loosely mounted upon such shaft 28. Aspring 33 tends to press these hubs together such spring pressing at oneend against the outer side of the casing and at the other end against awasher 34, or if desired, a ball bearing, bearing upon the hub 32. Inthe two forms previously described, a spacer was provided between thehubs of the brushes, but in this form a pair of rollers 35 serve tospace the hubs of the brushes. These rollers run in grooves 36 formed inthe hubs of the brushes and are carried upon a transverse shaft 37 whichis anchored at 38 in opposite sides of the casing and is bowed upwardlyat its central portion 39 to avoid contact with the shaft 28. It will beseen that when the dirush 29 is rotated in one direction, the brush 31is caused to rotate in the Yopposite direction through the medium of therollers 35.

It will thus be seen that a simple, light weight shoe shine brush hasbeen provided in which a pair of rotary brushes are posil tioned closelyadjacent each other and are axially alined so that by relatively smallposed brushes;

lshoe is subjected to alternate movement of the device back and forththe brushings in opposite directions.

claiml. A portable device vfor shining 'shoes comprising a pair ofaxially alined, juxta-V means for simultaneously` causing said brushesto rotate in opposite directions; and manual means for positioning saidbrushes upon the shoe, whereby shoes may be polished without them .fromthe feet of the wearer.

2. A device for shining shoes comprising acasing, a handle mounted uponsaid casing whereby said casing ma be manually manipulated, a shaftexten ing transversely of said casing, la pair of juxtaposed brushesloosely Vmounted upon Vsaid shaft and projecting outwardly froml saidcasing, and

driving means for simultaneously rotating said brushes in oppositedirections.V

3..A device for shining shoes comprising a substantially semi-circularcasing having l Van open portion, a manipulating handle supporting .saidcasing, a shaft extending transversely across said casing, adjacent saidopen portion, a pau-'of juxtaposed alined removing Y brushes looselymounted Vupon said shaft, a drive shaft passing through said handle andinto the said casing, and means for operatively connecting said driveshaft and said brushes, whereby said brushes are caused to rotate inopposite directions upon rotation of said drive shaft.

'4. A shoe shine device comprising a casing having an open portion, amanipulating handle supporting said casing, Vadrive shaft extendingthrough said handle and into said asing, a pair of pulleys mounted uponsaid Y rive
